1 Claim. 1

This invention relates to a space heating device and has for an objectthe provision of a device of this type adapted for use with stoves fordirecting heated air throughout the interior of a room. It is well knownthat the use of stoves for heating relatively large rooms are notsatisfactory due to the fact that the heat is not radiated a sufficientdistance from the stove, therefore, the stove is only useful in heatingthe area of a room immediately adjacent thereto.

It is an object of the present invention to provide a device adapted tobe mounted upon a stove for directing a stream of heated air throughoutthe entire interior of a roo-m. Devices heretofore employed foraccomplishing this purpose have usually consisted of a heating unit andelectric fan for directing heated air outwardly from the heating unit.

The present invention contemplates the provision of a tubular stackdisposed in an upright position above a stove for the passage of heatedair therethrough. When the air within the tubular stack is heated, itproduces an upwardly flowing hot air stream having sufficient velocityto direct heated air a relatively long distance from the stove.

It is a further object of this invention to provide a space heatingdevice which is relatively inexpensive in construction, simple inoperation, and which will not readily get out of order.

This invention embodies other novel features, details of constructionand arrangement of parts which are hereinafter set forth in thespecification and claim and illustrated in the accompanying drawingwherein:

Fig. 1 is a side elevational View showing a space heating deviceembodying features of this invention.

Fig. 2 is a plan view of same.

Fig. 3 is a sectional view taken along the line 3-3 of Fig. 1.

Referring noW to the drawing for a better understanding of thisinvention, the space heating device is shown as comprising a tubularstack 6 provided with an enlarged air inlet portion l. As illustratedmore clearly in Fig. 3, the enlarged air inlet portion is preferablyprovided with an upturned annular ange 8 to receive a tubular ring 9.The tubular ring 9 is adapted to be riveted or otherwise secured to theannular flange 8 to receive the lower end of the tubular stack 6. Thetubular stack 6 is preferably detachably mounted upon the annular ring9. Therefore, it is desirable that the annular ring 9 extend upwardlywithin the stack 6 a sufficient distance to prevent accidentaldisplacement of the stack from the ring. The air inlet portion 1 is alsoprovided with an annular flange portion II. Secured to the face of theflange Il is provided a pair of supporting members I2 which arepreferably formed of strip material having their ends welded to theflange I! and their intermediate portions I3 disposed in predeterminedparallel spaced relation to the face of the flange II by means ofvertical portions I4.

In the operation of a space heating device of the type shown anddescribed, the air inlet portion 'I is positioned upon the top of astove I6 with the stack 6 mounted in position upon the annular ring 9.Heat from the upper surface of the stove is radiated to the aircontained within the interior of the air inlet portion 'I and stack 6,thus causing the air within the stack 6 to rise upwardly at a relativelyhigh velocity. During the rise of heated air within the stack 6,unheated or partially heated air is drawn inwardly through the spacedefined by the annular flange Il and the top of the stove. When theupper end of the stack 6 is positioned in spaced relation to a ceilingI1, as illustrated in Fig. 1, the rapidly moving stream of heated airpassing upwardly within the stack 6 is directed against the ceiling andthence laterally and/or downwardly for heating portions of the roomremote from the stove I6. It has been found during the operation of thisdevice that the heated air stream ows a considerable distance from thestove and in the form of a whirl and thus conveys heat to variousportions of a room. In heating the interior of a room by means of astove and space heating device of the type shown and described, it willbe noted that the continuous circulation of air through the stack 6 willeventually cause all the air contained within a room to be heated due tothe fact that the relatively cold air is drawn inwardly from adjacentthe oor and directed outwardly at relatively high velocity from thestack 6. Thus, if the stove I5 is of sufficient size, all of the airwithin a room will be directed through the stack within a relativelyshort period of time to provide a desired room temperature.

While this invention has ben shown in but one form, it is obvious tothose skilled in the art that it is not so limited but is susceptible ofvarious changes and modifications without departing from the spirit andscope of the claimed invention.

I claim as my invention:

In a space heating device for conducting heated air from adjacent thetop surface of a stove to and adapted-toppen'- into a room and disperseheated air in same, said stack supporting means comprising a pair ofU-shape supporting legs having their ends secured to the inletend'ofsaidf.
